A bicyclist traveled with a speed of 12 km/h from a camping ground to a station, located 60 km away. Write a formula expressing

the dependence of the variable s on t, where s is the distance between the bicyclist and the station in km, t - the duration (time) of his travel in hours. Using the formula, find:

The bicyclist starts at the camp and travels 12 km/h. So in t hours, the bicyclist travels 12t km.  The remaining distance (from the bicyclist to the station) is 60 - 12t, the whole distance, 60 km minus the distance the bicyclist has traveled.

s=60-12t

Now you can answer questions such as "how far was the bicyclist from the station after 3 hours?"  Substitute 3 for t.  s = 60 - 12(3) = 60 - 36 = 24 km.

<em>Answer:</em>

s=18

<em>Step-by-step explanation:</em>

First of all, the formula is s=60-12t. thanks to the person who answered this question first (teehee)

S=distance and t=duration.

We also know that the distance is 60 km, the bicyclists's speed is 12 km/h, and the <u>duration</u> for this example is 3.5 hours.

So, using the formula, we substitute all the variables and s=18.

Thanks!

Also, for how the formula is what it is, look at the previous answer cuz yea.

Maybe this helped?

M(-3,2) is the midpoint of AP. If A has coordinates (-1,5), what are the<br> coordinates of P?
Inessa05 [86]

Answer:

<h3>            P(-5, -1)</h3>

Step-by-step explanation:

If M is midpoint of AP then:  

x_P-x_M=x_M-x_A\qquad\quad\ \wedge\qquad y_P-y_M=y_M-y_A\\\\x_P-(-3)=-3-(-1)\qquad\wedge\qquad y_P-2=2-5\\\\x_P+3=-3+1\qquad\quad\ \wedge\qquad\quad y_P-2=-3\\\\x_P=-3+1-3\qquad\quad\ \wedge\qquad\quad y_P=-3+2\\\\x_P=-5\qquad\qquad\ \wedge\qquad\qquad y_P=-1

Consider the probability that at least 96 out of 152 computers will not crash in a day. Assume the probability that a given comp
djyliett [7]

Answer:

0.2061

Step-by-step explanation:

Probability (no crash) = 66% = 0.66

Average (no crash) expected out of 152 computers = 0.66 (152) = 100.32

Standard deviation 's' =  √ [ (154) (0.66) (1-0.66) ] = √ (154) (0.66) (0.34)

=  √ 34.5576 = 5.87

P (x <u>></u> 96) = 1 - P (x <u><</u> 95)

z= (x - u) / s ;  x = sample mean = 95.5 (continuity correction factor = 0.5) ,   u = population average = 100.32

z = (95.5 - 100.32) / 5.87 = 4.82 / 5.87 = 0.82

P (x <u><</u> 95) = P (z <u><</u> 0.82) = 0.7939

P (x <u>></u> 96) = 1 -  0.7939  = 0.2061

An angle measure of 82 degrees is equivalent to ____ radians. Round your answer to the nearest hundredth when necessary.
tester [92]
2pi radians=360 degrees
rato and proprtion
xrad/(2pi)=ydeg/360
xrad/2pi=82/360
times both sides by 2pi
xrad=164pi/360
xrad=41pi/90
aprox pi=3.141592
xrad=1.431
round
xrad=1.43 radians


1.43 radians=82 degrees
